(it the, shell or casing 10 and supper-ting or an annular flange 20 the re leetor, anrlfla conducting spring in eleetrieal connection with the can 12 and engaging the lower or rear enrl of the battery. (hie terminal of the lamp engages the forward eml of the battery at The can 12 is screwed upon 1 metal hancl 23 which in eleetrieal connew tion with a conducting: strip cZ-l tllllltllfllll within the material of the casing or shell ill.

S 0 ill;

nner surface of the box-like presses with a light spring action at its end bedded a conducting strip 26, and the circuit from opposite ends of the. battery is through the conducting strips 24, 26.

The shell or casing 10 is preferably formed from vulcanized fiber and the conducting strips 24, 26 are at first in one strip and positioned by the winding of the sheet of fiber upon said strip during the formation of the shell or casing, the strip being located between the convolutions of the sheet, so that finally when the shell or casing'is completed the single strip of metal to constitute the conductors 24, 26 is embedded therein and extends lengthwise thereof and is not only secured in place but protected from contact with the battery. The original strip from which the conductors 2i, 26 are formed I'sever at 27 to form a break in the strip and thus create the independent conductors or strips 24, 26 from the single original strip. The circuit through the lamp is made and broken at the adjoining ends of the conductors 24, 26 and therefore said ends must be exposed to the action of a circuit closer or switch, and in carrying out my invention I form a transverse groove 28 in the outer surface of the shell or casing 10 in line with the break 27 between the conductors2l, 26, thereby exposing the adjacent ends of said conductors and providing a space into which the circuit closer or switch may be projected, when desired, into engagement with said ends of said conductors. Upon the outer face of the shell or casing 10 and concealing the groove 28 therein is secured an escutcheon plate 29 which may be of ornamental outline and has an outwardly projecting box-like section 30 upon which is mounted a thumb-piece or transverse slide 31 which carries an inwardly projecting finger 32 whose inner end engages a transverse circuit closer spring or switch 33, the latter being secured to the escutcheon and also against the outer face of the shell or casing by means of an eyelet 34, this eyelet being used also to secure one end of the escutcheon in place. The other end of 29 is secured to the shell or casing 10 by means of an eyelet 35. The finger 32 is formed upon a plate 36 which has a lug 37 riveted in the center of the thumb-piece or slide 31 and said finger 32 projects from said plate through a transverse slot 38 formed in the outer face of the box-like portion 30 of the escutcheon 29. Within the box-like por tion of the escutcheon there is secured upon the finger 32 a thin plate 39 which engages the portion 30 and portions against said surface. The plate 39 serves to secure the thumb-piece 31 in position on the box-like section 30 and at the same time permits said thumb-piece to have a proper transverse movement.

The circuit closer or spring switch 33 is,

. thumb-piece versely in a direction toward the free end ofthe escutcheon 29. The circuit closer or is bent slightly inwardly, as at 40, to form a pocket for'the inner end of the finger 32 when the thumb-piece or slide 31 is in its normal switch the latter is bent outwardly, as at 41, to form a cam surface against which the inner end of the finger 32 will ride when the or slide 31 is moved transthe said circuit closer or switch, with the result that said end of the circuit closer or switch will be forced inwardly against the exposed adjoining ends of the conductors 24, 26, thereby to complete the circuit through the lamp and battery. I .bifurcate the free end of the circuit closer or switch 33, as shown at 42, so as to render the two parts at the free end of the circuit closer or switch independently yieldable to the conductors 2t, 26, and thereby I am enabled to secure a firm, electrical engagement of the switch with the conductors 2%, 26 regardless of any small defects or irregularities which otherwise, were the end of the switch not bifurcated, might prevent-the switch from engaging both of the conductors 24., 26. The groove 28 in the outer surface of the shell or casing 10 permits the circuit closer or switch 33 to avea hinged action and also enables the free end of the circuit closer or switch to reach 26 when the slide purpose.

The operation of the circuit closer mechanism will be readily understood without further special description. lVhen the thumbpieceor slide 31 is in its normal position shown in Figs. 1 and 3, the switch 33 will stand free of the conductors 24, 26 and the circuit will be broken at the space 27 between the adjoining ends of said conductors. \Vhen it is desired to light the lamp the thumb-piece or slide 31 will be moved transversely or toward the left, looking. at Fig. 1. so as to carry the finger 32 upon the projecting portion all of the circuit closer or switch, and thereby cause the free end of said switch to engagethe conductors 24, 26 and complete the circuit.- When it is desired to extinguish the light the thumb-piece or slide 31 will be moved back to its initial position shown in Fig. 1, carrying the finger 32 from the outwardly projecting portion of the switch .33 and allowing said switch of its own resiliency to spring outwardly from the conductors 24, 26, thereby breaking the circuit at the space 27 between said conductors. The upper end of the conductor 26 is in engagement with the cap 19- which is a the conductors 24,

31 is moved to effect that of the box-like portion 30 i urea 11crcii1be'f11 e described v1 11g 1 ca an electric 111,1 1 1 1"11 1gnorterm 111111 1111111 hie-tors 111011; 511 1 '1 1 mg beits recessed "Apose 11dnt 1-1111 p -.-.1i2;-1 111 1311111 111111l111to1s, a .mbered escutcheon plate secured 11 o er a; '11 rece a spring switch in the 1.l111111ber 111 said plate and at one end 1111' held and having near its tree end an ward proj1 and 11 slide mounted on 111d guided by said plate and having a linger in be 111ovr-11 along the said switch 111111 by en- 'aging said projecthri force the free c1111 01 the switch against the adjoining ends 111 110.11 said conductors.
